From the point of the view of significant figures which of the following statements are correct ?
(i) `10.2 cm + 8 cm = 18. 2 cm `
(ii) ` 2.53 m - 1.2 m = 1.33 m`
(iii) `4.2 m xx 1.4 m = 5.88 m^(2)`
(iv) `3.6 m //1.75 sec = 2.1 m//s`

A

(i) and (iv) only

B

(ii) and (iii) only

C

(iv) only

D

(ii) and (iv) only

Text Solution

Verified by Experts

The correct Answer is:
A
In addition or subtraction, the final result should retain as many decimal places as are there in the number with the least decimal places. In multiplication or division, the final result should retain as many significant figures as are there in the original number with the least significant figures.
Hence, according to above rules (i) and (iv) are correct.
